One rule the old pm at my old work had regarding labour hire. It was never use Australians through labour hire. Reason being people on working holidays often need the work to fund their airfare home once their visas are up, so whilst they have overseas qualifications, they typically want to work. Maybe its not always the case, like anything there are potatoes out there. But his refusal for Australian labour hire people was you only go into labour hire if you cannot get a full time job in your industry. And usually theres a good reason for that. So nothing racist, this pm was a proud bogan.
What i used to find almost humours was being on site with other contractors from non English speaking backgrounds and all day you could chat and have a laugh with them. But the moment they stuff up and their leading hand gets up them, the instantly forget how to speak english.
